Description
Technical Field
The invention belongs to the technical field of automobile virtual calibration test, and particularly relates to a wire harness device for automobile virtual rack test.
Background
With the continuous increase of the quantity of the motor vehicles on the market, the problems of energy consumption and environmental pollution are increasingly highlighted, more severe oil consumption and emission limit value regulations are provided in the country to promote the research of accelerating energy conservation and emission reduction of host plants and vehicle enterprises, the fuel consumption limit value of GB 30510 plus 2018 heavy commercial vehicles is issued in the country in 2018, the fuel consumption of trucks with different total design masses is reduced by 11.5-15.4% compared with the limit value of the upper stage, and the oil consumption limit value standard working group of the fourth stage of the heavy commercial vehicles is formally started in the 2020 and 8 months. The six national regulations of heavy-duty vehicles also require that the engine and the whole vehicle are respectively authenticated, the combined management and control of emission and oil consumption is implemented, and meanwhile, higher requirements on production consistency and in-use conformity are also provided. Along with stricter regulation requirements, the supervision and punishment are increasingly stricter, and the method is based on the upper law, namely the atmospheric law. The emission standard and the oil consumption standard in the lower stage have more severe requirements on the oil consumption emission limit value, meanwhile, the test working condition can also face the problem of China working condition switching, and for heavy vehicles and engine enterprises, the challenge of meeting the requirements of the oil consumption emission regulations of the heavy vehicles is huge. Therefore, it is very necessary to perform pre-evaluation tests on fuel consumption and emission of the vehicle in the early development stage of the vehicle.
However, due to the particularity of the heavy-duty vehicle industry, an engine is often matched with various different types of vehicles. Taking Yuchai engine as an example, the whole vehicle with different enterprises and different configurations matched with one engine can reach hundreds, and the engine covers five basic types of buses, heavy trucks, dump trucks, tractors, city buses and the like, and also comprises various professional vehicle types such as a mixer truck, a sprinkler and the like. For engine enterprises, fuel consumption and emission conditions matched with the vehicle models need to be mastered. For vehicle enterprises, it is also necessary to know the compliance risk after matching the engine. However, if the emission and fuel consumption regulations are verified for each vehicle type, it is impossible to complete the work. Therefore, the emission and oil consumption levels of the vehicles are evaluated, and the risk of compliance of the oil consumption emission regulations of the vehicles is identified, which is vital to the enterprises and is the maximum pain point faced by the enterprises at present.
The six national regulations for light vehicles also require the type certification of real road emissions (RDE) and fuel consumption. Meanwhile, with the implementation of the fifth-stage fuel consumption standards (GB 19578-. The application of the new technologies brings new development requirements on fuel consumption and emission control of light vehicles. In addition, due to the great reduction of the development cycle of the light vehicle, the development work of the light vehicle also faces the pressure of development cost control and development efficiency improvement.
Aiming at the current situation, in order to solve the industry pain point, a method for testing the oil consumption and emission of heavy vehicles based on a vehicle virtual rack is provided. The engine and whole vehicle circulation condition test is carried out on the vehicle virtual rack by using the engine and whole vehicle simulation model, so that the fuel economy and emission performance of the engine and the whole vehicle under the transient condition are accurately and truly evaluated.
In order to realize the functions of the automobile, a plurality of auxiliary systems are needed, such as a wire harness system for realizing signal transmission and power supply among electric devices, if an engine is compared with the heart of the automobile, the wire harness system is a neural network system of the automobile, the running of the automobile is realized by connecting various systems of the automobile, and the automobile circuit does not exist without a wire harness.
